What is the main benefit of drilled and slotted rotors?

Drilled holes help to vent heat and moisture away from the rotor surface, which can improve braking performance, especially under heavy use. The slots also help to clear away brake dust and gases, maintaining a more consistent contact between the pad and rotor.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. It does not include brake pads or any mounting hardware. It is recommended to inspect your existing hardware and pads when replacing rotors.

What is the black finish on the rotor?

The black finish is a coating applied to the rotor surface. It helps to protect the rotor from rust and corrosion, especially during storage and transit, and also provides an updated aesthetic appearance.
